The purpose of this study is to compare the verbal control modes used by fathers or mothers toward their children. The subjects of this study are 148 fathers and 159 mothers whose children attend kindergartens. For data analysis, t-test, one-way ANOVA and Scheffe's test, Pearson's correlation, and two-way ANOVA were used. The major findings are as follows: First, the status-oriented verbal control mode was most frequently used by both fathers and mothers, while the order-oriented verbal control mode was used less frequently by parents. Second, both fathers and mothers used three verbal control modes more often toward boys than toward girls. Third, the comparison of verbal control modes between fathers and mothers revealed that mothers, rather than fathers, used three verbal control modes more frequently toward their children. Fourth, mothers with higher education, rather than fathers with higher education, used the status-oriented verbal control mode and personality-oriented verbal control mode more frequently toward their children.

Phosphors of $Eu^{2+}$ doped alkaline earth aluminates MA$l_2O_4:Eu^{2+}$ (M=Sr, Ba, Ca) have been prepared by sol-gel process and their characterization of photoluminescence and photocurrent properties have been performed. The phosphors prepared by sol-gel process, due to its advantage of better homogeneity and low synthetic temperature, was synthesized as single phases at lower temperature than the solid-state process; $800{\sim}1000{^{\circ}C}$ for 6 h under mild reduction atmosphere (Ar- 3% $H_2$). It was confirmed that SrA$l_2O_4:Eu^{2+}$ composition revealed the most excellent properties in the brightness and photocurrent.

In this study, a nonlinear one degree of freedom ferromagnetic suspension model is used to design a vibration isolation system. The resulting voltage controlled electromagnetic and mechanical system is a third order, highly nonlinear systems. We proposed the adaptive sliding mode control(SMC) scheme for this system. The presented control scheme is based on the Variable Structure System(VSS) and adaptive control theory. The only available sensor is an air gap sensor and imperfect knowledge of the resistance in the electrical circuit is treated by including adaptive update law. The disturbance force is applied to the suspended mass. And we verified that the proposed control scheme is the feasible through a computer simulation.

젖소가 사료를 먹는 양은 생리학적으로는 혈당과 포만감에 의해 조절되며, 일반적으로 국내에서 사용하는 사료섭취량은 미국 NRC(국립과학연구소, The National Research Council)에서 실험 통계학적으로 나온 결과를 기준으로 품종, 산차, 체중, 비유시기, BCS(체점수), 기온 등을 고려하여 설정되었다. 최근 우리나라에서 풀의 사용량이 갈수록 증가하고 있는데 이에 따른 수익도 있지만 문제점은 없는지, 특히 생리학적인 면에서 한번은 짚고 넘어가야 한다고 보기 때문에 필자가 언급코자 한다.

S-Adenosyl-L-methionine : protein-carboxyl 0-methyltransferase(prorein methylase II) has been purified from bovine skeletal muscle approximately 6,600-fold with a 7% yield by combination of ammonium sulfate precipitate, Sephadex G-75 chromatography, S-adenosyl-L-homocysteine-Sepharose 4B chromatography and hydroxyapatite chromatography, and then its characterizations and possible roles were investigated. The enzyme showed a optimum pH around 6.0. It was heat labile, inactivated by heat-treatment at 60℃ for 6 minutes, and when stored at -20℃ in the presence 10% glycerol, its activity has almost stabilized in 6 months. Copper ion(Cu^2+)and zinc ion(Zn^2+)were a potent inhibitors, the activity being completely inhibited at 0.25 mM and 1 mM respectively, The inhibition of copper and zinc ions were recovered 94%, 75% of its activity by adding 4 mM of EDTA, respectively. The apparent Km value for S-adenosyl--L-methionine was 2.86 x 10^-6 M. Kinetic analysis of enzyme in the presence of 30 uM copper ion showed that the nature of the inhibition to the enzyme was noncompetitive considering that Km was constant and Vmax was decreased. Histone IIA, immunoglobulin A and trypsin inhibitor were relatively good substrates for the enzyme. The enzyme activity was completely inhibited by 0.5 mM p-hydroxymercuribenzoic acid, but all of the activity was recovered in adding 10 mM mercaptoethanol, and the molecular weight of the enzyme was 24,000. Sarcolemma and sarcoplasmic reticulum of the skeletal muscle were good substrates for this enzyme and ^3H-CH_3 group was incorporated to 0.63 and 0.96 pmoles/mg protein/min, respectively. The carboxylmethylation of the sarcolemma of the skeletal muscle occurred in the 5 protein fractions(M. W. : 45,000, 22,000, below 14,400etc.) and that of sarcoplasmic reticulum occurred in the 7 protein fractions (M. W. : 100,000, 45,000, 22,000, below 14, 400 etc) by SDS/polyacrylamide gel electrophoresis. Among these molecular weight 22,000 was strongly methylated. These results discuss that protein methylase Il may play some roles in regulating physiological function of sarcolemma and sarcoplasmic reticulum of skeletal muscle.
